-' The present invention relates to cellular cartons, the interior of which is divided into cells or compartments by means of transverse and longitudinal partitions, and has'for its object to improve cartons of this type.

One of the most common forms of cellular cartons is that in which a dozen eggs, arranged in two rows, are housed or packaged. Viewed in one of its aspects,`the present invention may be said to have for its object to produce a simple and novel carton ofthis general type, composed vof a single blank properly shaped, folded and glued.

In one of themost common forms of egg cartons the cross -partitions are not only formed as integr/al parts of the body ofthe carton, but they are suspended at their upper ends from the upper portions of the front, and rear walls, and upon setting up the cartons, these cross partit-ions are swung down so as to stand at right angles to the plane of the top of the carton. Viewed in one of its aspects, the present invention may be said tohave for its object so to construct tudinal partition, which vcooperates with the cross partitions, is formed by folding the bot-- the claims; but, for a full understanding of' my invention and of its objects and advan- 40 tages, reference may be had to the following detailed description takeninceirection with the accompanying drawings, wherein Figure l is a perspective View of one ofmy improved cartons, set up ready for use, the

I

Referring to Figs. l to 4 of the drawings, 60 it will be seen that my improved carton consists ofa body member having front and rear walls l and 2, a bottom wall in the form of an inverted V andv consisting of two sections 3 and 4 sloping downwardly toward the front 65 and the rear, respectively, from the longitudinal center, together with cover 5 and cross partitions 6. The cross partitions are connected by triangular pieces 7 to the upper edge of the front walls, and by suitable triangular pieces 8- to attaching strip 9 that is glued to the rear wall. Cooperating with the transverse partitions is longitudinal partition 10 rising from the apex or ridge in the bottom wall through the transverse partitions. This longitudinal partition is preferably formed by providing between the bot- 1 tom wall sections 3 and 4 another section that is twice as wide as the height of the lon'gi tudinal partition; whereby, upon properly folding the blank, the bottom wall and the longitudinal partition in cross section resembles an inverted Y whose stem is of double thickness and extends farenough up to engage vwith the under side of the cover when the cover is closed. By this means,l assuming that thelongitudinal partition is held up, it serves as: a support forl the cover along the It is highly desirable that the cross parti- L tudinal partition from moving downward after the carton had once been set up, there will be no danger of collapse of the carton or of partial disassembly in the use of the carton.

The slotting of the cross partitions involves simply the placing of two comparatively short slots 11 and .12, extending downwardly from the upper edge and downwardly from the lower edge, respectively, at thelongitudinal center of the carton. The slotting of the two sections constituting the longitudinal partition is best shown in Figs. 2 and 4.

y.Pairs of long, 'straight slits 14,' 14 are cut transversely of the section 10 on opposite sides of and at some distance from the central crease line 15 along which the section 10 is folded. Two curved slits 16, 16, with their concave sides directed toward the corresponding straight slits, are cut into the section 10 adjacent to each pair of straight slits. The two curved slits of each pair meet about at the juncture of the crease line 15 and a line forming a continuation of the corresponding straight slits; and each curved slit also meets the corresponding straightl slit between the ends of the latter. Slits are also cut in the section 1() parallel with the line 15 and eX- tending from the ends of the straight slits nearest the line 15 to the corresponding curved slits. Other short, diagonal slits are cut from the crease line to the curved slits, these short slits lying on the convex sides of the slits 16.

In this way groups of little windows are formed inthe section 10 and, when the latter j' is folded along the line 15, as shown in Fig.

2, it will be found to contain a series of vertical slots, extending through the top edge of the longitudinal partition formed thereby; each slot having a flaring mouth 17 at the top, being pinched shut just below the mouth or entrance and then again widening as indicated at 18 and finally becoming again a mere slit, namely, the end of the slit 14. The material on one side of each slot forms a triangular nose or lug 19, one free edge of which constitutes one edge of the flaring mouth -while the other free edge constitutes a horizontal, downwardly-facing shoulder extend'- '1 across the top of the wide part 18 of the s ot.

The parts are so proportioned that the slots in the longitudinal'partition register with the transverse partitions when the latter are swung down; the slots 11 are about equal in depth to the height of the noses or lugs 19; and the slots 12 are only about as deep as the distance between the lower ends of the slits 14 and the base of the longitudinal partition. The result is that when the carton is set up, as shown in Figs. 1 and 2, the noses or lugs 19 engage in the slots 11 in the tops of the cross partitions and hold the longitudinal partition up; the slots 12 in the cross partition receive the base portion of the longitudinal partition; and a considerable portion of each cross partition is wedged into the lower end ofl the corresponding slit 14 below thev window 18. thereby locking the transverse partitions against swinging movements.

In setting up the carton 4the cross partitions must first be swung down into vertical positions and the longitudinal partition be then moved up through the same; and, obviously, separation of the longitlidinal partition from the cross partitions can be effected only by a reverse relative movement, namely, a downward movement of the longitudinal partition. Therefore, by locking the longitudinal partition in its raised position, all accidental displacement of parts that would detract from the efficiency of the carton is prevented'.

The operation of setting up the carton is illustrated in Fig. 3 which shows the body of the carton opened up into'a shell of about twice the height of the final product. After the cross partitions are swung down, as shown, the lower part Iof the shell is folded into the condition indicated in dotted lines in Fig. 8, the folding being then continued until the condition illustrated in Fig. l is reached.

It will be seen that when the carton is set up, the double longitudinal partition presents practically a continuous upper edge to support the cover and thus makes the vcarton very strong in resisting vertical crushing stresses.

The angle at which the sections of the bottom wall slope may be varied as may the general design to change the shape of carton. Thus, in Fig. 5 I have illustrated a modification in which the sections 23, 24 and 30 corresponding to the sections 3, 4 and 10 in the other form, produce a comparatively shallow longitudinal partition and, with the front .and rear walls, 21 and 22, form two deep troughs below and at opposite sides of the longitudinal partition. The cross partitions 26 are made more forked than are the parti tions 6, in order to fill the valleys in the bottom of the carton, and the slots 12 are of course thereby brought closer to the top.

I claim:

A carton of the type described, comprising a single blank cut, scored and folded to forni a cover-locking strip, a cover, a rear wall, a rear bottom section. a rear longitudinal partition section, a front longitudinal partition section, a front bottom section, a front wall, cross partitions/'hinged to said front wall,

and an attaching strip hinged to the opposite side of saidvcross partitions and secured to the rear wall, said longitudinal partition sections being incontact and having down- Wardly extending yslots for receivin said cross partitions and hooks adjacent `t e top of said slots for engaging the upper portion of said cross partitions', the hooks adjacent the endcrosspartitions bein faced inwardly. In testimony whereof, I slgn this speciication. Y
